C. B. TOMS REPLACEABLE WEAR SHOE FOR MOWERS Filed April 23, 1940 i i I i I 1n ventor Patented Mar. 25, 1941 UNITED STATES PATENT OFFICE Application April 29,

1 Claim.

My invention relates to means for slidably supporting the cutter bar of a mowing machine on the ground, and particularly to a replaceable shoe for this purpose, and the primary object of the invention is to provide a shoe of this character which may be easily and quickly replaced when worn, and which can be made of material which resists wear better than the steel of the cutter bar support.

Other important objects and advantages of my invention will be apparent from a reading of the following description of the appended drawing wherein for purposes of illustration I have shown a preferred embodiment of the invention.

In the drawing- Figure 1 is an end elevational view of the cutter bar showing the shoe secured to the bottom thereof.

Figure 2 is a top plan view of the shoe. Figure 3 is a bottom plan View of the shoe. Referring in detail to the drawing, the numeral 5 generally designates the bracket on the laterally inward end of the cutter bar support I2, the latter having an upturned flange 6 at its front edge 25 and a right angular flange II on its rear edge. Bolts I and 8 traverse holes 9 and I0, respectively, in the support to connect the replaceable preferably cast iron wear shoe which is generally designated Id. The top l3 of this shoe is curved to 30 conform to the contour of the bottom of the cutter bar support.

The shoe I4 is generally rectangular in trans- 1940, Serial No. 332,365

verse cross section and has countersinks I5 in its bottom to accept the heads of the. bolts 1 and 8. The shoe is sharply bevelled at its rear end as indicated by the numeral l6, has a flat bottom I1 and a gradually upwardly curved forepart With the shoe formed of cast iron the rate of wear is much less than that of steel as the shoe slides over the ground in the operation of the mower, and when worn can be replaced simply by loosening the bolts 1 and 8 and installing another shoe.

Although I have shown. and described herein a preferred embodiment of the invention, it is to be understood that I do not wish to limit the application of the invention thereto, except as may be required by the scope of the subjoined claim.

Having described the invention, what I claim as new is:

In combination with the cutter bar support of a mower, said support comprising a substantially horizontal part intermediate the rearward and forward edges thereof and having the forward edge portion upwardly and forwardly curved, a replaceable wear shoe elongated from front to rear and attached to the bottom of said horizontal part, the forward edge of said shoe being upwardly tapered and terminating to the rear of said upwardly and forwardly curved front edge portion, and means fastening said shoe in place.
